I am not sure what's your motivation of continue this motivation analysis on my feeling towards brutality.
I am always frustrated by the general skeptics applied on any comments where China and/or Chinese people were painted as the victim.
Doesn't it appear universal that feelings of people because of recent historical events should be respected?
To answer your question again, WWII is the most recent historical events... Of course people are going to have fresher memory of them. If people apply same emotional response to all historical events, USA should have a civil between Indian, African Americans, White, and Mexican people all the time.
Why such self-evident rationale automatically excluded from anything related to China/Chinese people? Was this racism? I cannot find any other execute...
